PROTECTIVE COVER.

Application filed October S, 1928. Serial No. 311,094.

This invention relates to protective covers for insulated tanks, boilers, stills, pipes, etc, and is applicable to all types of insulated containers including pipes designed to prevent the escape of either cold or hot air.

Another object of the invention is to pro vide a sheet metal cover for the protection of cork, asbestos and, other insulating materials, which cover is cheap of construction, may be readily applied, and will effectually prevent the passage of and protect the insulation beneath from all kinds of corrosion, acids, alkalies, water,.gases, fumes, and other causes of corrosion.

lVith the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings 1- Figure 1 is an elevation showing a tank provided with a cover constructed in accord ance with the invention.

Figure 2 is a plan view of the tank.

Figure 3 is an enlarged fragmentary sectional view taken substantially on the line 33 of Figure 1.

Figure 4-. is a fragmentary view showing the upper edge of one of the metallic strips with a hanger mounted thereon.

Figure 5 is a fragmentary view showing the adjustable connection for the retaining bands.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the cover which constitutes the present invention is adapted for the protection of insulation placed upon the outside of a tank. Thisinsulation may consist of cork bricks, asbestos, or any other suitable insulation and is indicated at 10, while the tank to which it is applied is indicate-d at 11. The insulation may or may not be covered with suitable roofing paper indicated at 12 and where this paper is used, it will of course be positioned between the insulation and the protecting cover which is indicated generally at 13.

The cover 13 is formed of separate sheets 14 of metal, preferably steel and these sheets are connected together with seams and grooves so as to provide an elongated strip which is placed around the tank with the ends of the strips secured together preferably by solder. As shown in Figure 1 of the drawings a number of these strips are placed around the tank one above the other, the num ber of strips of course being governed by the height or length of the tank. The upper edges of the strips thus formed carry substantially S-shaped hangers 15. These hang ers are preferably made of sheet metal straps shaped as shown in Figures 3 and a of the drawings with the inner ends of the straps extending over the upper edges of the strips to which they may be secured by rivets or other suitable means. The hangers 15 receive the lower edges of the next adjacent tank encircling strip with the lower edges overlapping the upper edges of adjacent strips.

Surrounding the strips are'metal bands 16, one of these metal bands being placed in each of the hangers while preferably two of the bands are placed around each strip between the hangers. The bands 16 are of sectional form shown in Figure 2 and the sections have their adjacent ends connected by means of adjusting bolts 17 which pass through apertured lugs formed in the ends of the sections. The bands 16 may thus be properly adjusted around the tank.

The top of the tank shown is dome shaped and is formed of sheet metal plates 18 whose edges overlap. The plates 18 are secured in place by screws 19 or other suitable fastening devices, the plates being seamed t0- gether and soldered, while the screws or fastening devices 19 are likewise soldered.

The inner face of the cover is painted with a suitable paint to prevent rusting and pre serve the sheets while the outside is similarly painted and may be covered with one or more coats of aluminum paint.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is:

1. In combination with a container having an insulated cover, a protecting cover comprising sheets of material arranged circumferentially around the container, circumferentially spaced hangers extending from the upper edges of said sheets and adapted to receive the lower edges of the next adjacent sheets, and means to secure the sheets around the container.

2. In combination with a container having an insulated cover, a protecting cover comadapted to be arranged circumferentially around the container, substantially S-shaped hanger straps extending from the upper edges of the strips, said hanger straps being adapted to receive the lower overlapping edges of the next adjacent strips, and adj ustable straps extending around the strips to secure the latter around the container.

In testimony whereof I aflix my signature.
